中文摘要	封育是恢复退化草地最常用的方法之一,然而封育在草地植物及土壤恢复中的作用尚存争议,尤其在荒漠中,为了进一步评估封育对荒漠植物和土壤性质的影响,本研究以准噶尔荒漠3种典型的植物群系为研究对象,应用高通量测序技术,系统分析了封育前后植物、土壤的差异。结果表明,3种荒漠植物群系的土壤有机碳、全氮和全磷含量封育后有一定的增降变化,但差异不显著;封育后伊犁绢蒿群系植物高度、盖度、地上生物量和物种丰富度分别提高了58.99%、59.35%、33.29%和51.21%;白梭梭群系分别提高了15.49%、33.52%、20.85%和5.13%;盐生假木贼群系分别提高了83.80%、31.51%、76.66%和33.33%。封育后3种植物群系细菌多样性也存在差异,其中伊犁绢蒿群系平均OTU数量和Shannon-Wiener指数显著增加了12.74%和2.92%;白梭梭群系平均OTU数量和Shannon-Wiener指数均显著升高了17.08%和3.17%;盐生假木贼群系平均OTU数量和Shannon-Wiener指数均封育后虽有高低变化,但差异不显著。封育显著增加了荒漠植物、土壤微生物多样性以及荒漠植物群系群落生产力,但封育后荒漠土壤养分含量有一定的增加,但差异不显著。这些研究表明,封育是恢复荒漠生态的有效方法,但可能对土壤养分的固存意义不大。
英文摘要	Enclosure is commonly used in the restoration of degraded grasslands.However, the effects of enclosure on grassland plant and soil restoration remain controversial, particularly in deserts.To assess the effects of enclosure on desert plants and soil properties, using high throughput sequencing, the differences between plants and soil were systematically analyzed before and after enclosure construction.The soil organic carbon, total nitrogen and total phosphorus contents of the three desert flora increased and decreased, but the difference was not significant;enclosure increased plant height, coverage, aboveground biomass, and species richness by 58.99%,59.35%, 33.29%, and 51.21%, respectively, in a Seriphidium transiliense formation;by 15.49%, 33.52%, 20.85%,and 5.13%, respectively, in a Haloxylon persicum formation;and by 83.80%, 31.51%, 76.66% and 33.33%, respectively,in an Anabasis salsa formation.For soil bacteria, enclosure significantly increased the average number of operational taxonomic units and Shannon-Wiener index by 12.74% and 2.92%, respectively, under S.transiliense formation and by 17.08% and 3.17%, respectively, under H.persicum formation.However, enclosure had no significant effect on the average number of operational taxonomic units or Shannon-Wiener index under A.salsa formation.Enclosure significantly increased desert plants, soil bacterial diversity, and desert plant community productivity;however, the increase in soil nutrient content was not significant.These results demonstrate that enclosure is effective for restoring desert ecosystems but may have little effect on the soil nutrient content.
